* | EDAC, mce_amd: Print IPID and Syndrome on a separate lineYazen Ghannam2017-02-161-5/+4

There are cases when we can have a valid Syndrome but not a valid Address. For example, the MCA_SYND register can be used to hold more detailed error info that the hardware folks can use. It's not just DRAM ECC syndromes. There are some error types that aren't related to memory that may have valid syndromes, like some errors related to links in the Data Fabric, etc. In these cases, the IPID and Syndrome are not printed at the same log level as the rest of the stanza, so users won't see them on the console.

However, broken hardware and software is not something unheard of so warn about bank 4 errors. They shouldn't be coming from bank 4 naturally but users can still use mce_amd_inj to simulate errors from it for testing purposed.

| | | | | | | | | | | | | | | | | | | | | | | | | For Scalable MCA enabled processors, errors are listed per IP block. And since it is not required for an IP to map to a particular bank, we need to use HWID and McaType values from the MCx_IPID register to figure out which IP a given bank represents. We also have a new bit (TCC) in the MCx_STATUS register to indicate Task context is corrupt. Add logic here to decode errors from all known IP blocks for Fam17h Model 00-0fh and to print TCC errors.

* x86, mce: Add wrappers for registering on the decode chainBorislav Petkov2011-12-141-2/+2
| | | | | | | No functionality change, this is done so that in a follow-on patch all queued-up MCEs can be decoded after registering on the chain. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>

* EDAC, MCE, AMD: Drop local coreid reportingBorislav Petkov2011-10-061-19/+1
| | | | | | | | | MCE decoding code is reporting the core which encountered the error unconditionally now so drop this piece. Besides, it reported the coreid in the local processor package which is not that valuable as a datapoint. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
* EDAC, MCE, AMD: Print valid addr when reporting an errorBorislav Petkov2011-10-061-1/+3
| | | | | | | | | The MCi_STATUS bank has a AddrV bit which, when set, denotes that the corresponding MCi_ADDR MSR contains a valid address belonging to the MCE currently being reported. Dump it since it is definitely relevant information. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
* EDAC, MCE, AMD: Print CPU number when reporting the errorBorislav Petkov2011-10-061-2/+2
| | | | | | | | | Currently, correctable ECCs go through mcelog and do not print the scary MCE banner. In that case, however, reporting the core where the CECC happened is important information so dump it along with the decoded string albeit at risk of having a minor redundancy.

* amd64_edac: Cleanup NBSH cruftBorislav Petkov2011-03-171-1/+1
| | | | | | | | | Remove reporting of errors with UC bit set - this is done by the MCE decoding code anyway and this driver deals with DRAM ECC errors only. UC (NB uncorrectable error) doesn't necessarily mean it is a DRAM error. Remove unused macros while at it. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
